Vulnerability description
DayBreach CVE AI Research
CVE-2026-70609 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 39.8.7, 40.9.0, 41.2.0, and 42.0.0-beta.1, the mode option of webContents.openDevTools() was not sanitized before use by the DevTools frontend. If an attacker can influence this value, script under their control may run in the DevTools context, which in unsandboxed configurations has access to Node.js, including when untrusted input reaches the mode argument of openDevTools() or untrusted content calls openDevTools() on a webview it embeds. This issue is fixed in 39.8.7, 40.9.0, 41.2.0, and 42.0.0-beta.1.
